Sienna Miller's Rhys tattoo

The pair - who have denied they are more than just friends - were seen leaving a Dublin tattoo parlour where the 'Notting Hill' actor had an identical swallow etching to Sienna's inked on his wrist yesterday (01.10.07).

The "good pals" showed off their copycat body art as they strolled arm in arm through the city.

The move is bound to annoy Sienna's fashion rival Kate Moss, who has a swallow tattoo herself and used the emblem for the labels in her Topshop fashion range.

Last week, Kate accused the 'Factory Girl' actress of trying to copy her lifestyle by stealing her look and her friends.

The catwalk model has been close pals with Rhys, 39, for years and was said to be furious that Sienna, 25, and the Welsh actor are now inseparable.

Sienna and Rhys were recently seen kissing and canoodling in a dark corner of new London club Maya.

An onlooker said: "They were all over each other and didn't move from their little corner all night."

Rumours Rhys and Sienna were dating surfaced after the actor moved into the young star's house when his boathouse flooded in August.
